摘要： For deasphalting an asphaltene-containing hydrocarbon oil, employed is a hydrocarbon solvent of 3-8 carbon atoms, resulting in an asphaltic phase and a solution of deasphalted oil in the solvent. The solvent is then separated from the deasphalted oil, by passing the solution tangentially across an inorganic membrane of pore radii from 2 to 15 nonometers: the obtained filtrate has an increased solvent content and may be recycled. The deasphalted oil is selectively retained on the upstream side of the membrane.
